National Geographic channel has a cool TV series called "Doomsday Preppers". The show examines families/individuals who are preparing for a catastrophic event that will end all modern conveniences, like sources of food, fuel, utilities, etc. While some only stockpile basics like food and try to learn how to live the land without power and water sources, others train hours every day with military gear in the event of world chaos.

How far will you go to prepare for a worldwide doomsday event? I have enough basic supplies for a hurricane... that's about it.
